Rune Tip 4: Rune type progression

So now that you know where to get runes now you just need to farm for them. The best place to start is the scenario levels to get something on your monsters so they're not runeless. After you've beat Mt. White Ragon and can farm for energy, fatal, blade, and swift runes you have everything you're going to need to get started. Get any monsters you have that are attack type on fatal/blade with atk%/criDmg/atk% and any other monsters can be swift/energy with hp% and/or def%. Once you've got all your monsters with a basic set of runes it's time to hit Giant's Keep like it's going out of style. The scenario may be nice because you can farm for a specific rune but without the sub stats from the rune that drop from Giant's almost every rune you find is a 100% gamble when it comes to subs. So now that you're farming Giant's as a day job, you're going to want to go hard on until you can do at least b6 with a near 100% success rate. By Giant's b6 you should be ready for Dragon's Lair (depending on what monsters you have). Now that you're in Dragon's, again you're going to want a solid b6 team but just because you have a Dragon's b6 team doesn't mean it's necessary time for Necropolis. Farm Dragon's until you have enough violent runes to switch some of your monsters on swift to violent. About 9/10 times a monster that you have runed swift will be even better on violent (the wind and fire griffons, Bernard and Spectra, should be kept on swift though). Violent runes are the best rune set in my opinion. At the end of a monsters turn they have a 22% chance to get an additional turn which can flip a battle in an instant. Once you can get enough violent runes it's time to  start moving in the direction of Giant's b10 and/or Necropolis. Now Necro is different from Giant's and Dragon's. You want to bring only monsters that have multi-hit skills (skills that hit two or more times in one attack, like the harpu's first skill). Once you finally make it into Necro it could be worth your while to switch some of your fatal monsters to rage runes or vampire runes, energy runes can be traded for nemesis runes on most support monsters, and some monsters that do big damage could even take a set of destroy if you're using them for PvP (player vs player, aka arena, guild battles, and live arena).
